[PATCH v5 7/8] power: bq27xxx_battery: Define access methods to write chip registers

[Liam Breck <liam@networkimprov.net>]

From: Liam <github@networkimprov.net>

From: Matt Ranostay <matt@ranostay.consulting>

write(), read_bulk(), write_bulk() support setting chip registers,
e.g. with data obtained from power_supply_battery_info.
